Engell, S.S.Engell2022-03-082022-03-081989https://publica.fraunhofer.de/handle/publica/316378The paper deals with the scheduling problem in production units which consist of several subsystems, e.g. workshops or flexible manufacturing cells. A two-layer architecture is proposed were on the local level intelligent control units perform an optimization, and the upper-level scheduler coordinates the subsystems. The coordination problem is solved based on the mathematical description of the overall system in terms of the so-called minimax algebra.endecentralized controldezentrale Steuerungdistributed controlflexible manufacturing systemflexibles Fertigungssystemon-line control of manufacturing systemon-line Steuerung von Fertigungsprozessenoptimal schedulingoptimale MaschinenbelegungsplanungSteuerung004conference paper
